X-Head Porting....
I agree with demonracer whole heartedly. I had already most of the tooling and ready to give it a try. Took off most of the casting imperfections first and then started to work on the bowel areas under the valves. Using machinist dye painted the entire port area and “stoned” the painted areas clean, I did this procedure twice, intake and exhaust ports. Next I did intake gasket port matching, and then again for the intake manifold. The ports on the head and intake were way off in size and alignment, I would take care of this area first and then work back towards the valve areas.
What I learned, not worth the effort, for a street car, what do you think I made… maybe one or two horse power if that? BUT, I would at least gasket match the heads and manifold. .02 lol
